Product Details

Automatic Film Making and Winding Machine for Lithium Battery Making

Device Function Description

This machine is mainly used for making and winding cylindrical lithium-ion battery (cell). The working process is as follows:

after the positive and negative plates are unwinded actively, they are connected with the active unwinding diaphragm through the tension control, dust removal device, deviation correction device and static electricity

elimination respectively after welding the electrode lug and sticking the protective glue. Then they are introduced into the winding part and combined and wound according to the process requirements, and the termination tape is attached to realize the full-automatic film making, winding, automatic unloading and reaming (except for the ceramic diaphragm) during blanking, After short-circuit detection, the defective products are removed to the defective product box, and the good products are transported by the conveyor belt, and then transferred to the next process by the manipulator.

Equipment Features

1) Both positive and negative plates are welded by popular science full wave ultrasonic welding machine, with 35K positive electrode and 40K negative electrode (the welding machine can be selected by customers);

2) The rotary table is driven by the principle of servo motor and divider,which has the advantages of accurate positioning and fast production speed;

3) The winding needle adopts the advanced double half needle single side needle pulling mode, which can improve the winding speed;

4) All winding parts adopt slide rail structure with good clearance;

5) Adapt to production φ For the 13-26 size and 45-70mm width cell, it is only necessary to replace the reclaimer clip and change the parameters,which is convenient to change the process;

6) The man-machine is of sliding type, which makes refueling and operation more convenient and safe;

7) The tension can be controlled by proportional valve, and the tension can be controlled by sections;

8) The control method of integral rectification and material edge detection is adopted instead, which makes the design more reasonable, the judgment more accurate and the rectification speed faster;

9) The pole piece unwinding, post welding and cutting parts are equipped with a brush suction dust removal device;

10) The end tape is rolled and pasted, which is not easy to fold;

11) It adopts mechanical material handling and belt conveying, which can connect with the later process quickly and avoid cell damage;

12) Humanized design, friendly interface, easy operation and maintenance;

13) It has the function of automatic belt connection;

14) It has the function of abnormal alarm.
